The ratios of win to lose are 13 : 8, 13/8 and 1.625%
How to determine the ratio of win to lose?From the question, we have the following parameters that can be used in our computation:
Win = 50 more than lose
Win = 130
This means that
Win = 50 + Lose
So, we have
50 + Lose = 130
Evaluate
Lose = 80
The ratio is then represented as
Ratio = win to lose
This gives
Ratio = 130 : 80
So, we have
Ratio = 13 : 8
Express as fraction
Ratio = 13/8
Lastly, we have
Ratio = 1.625%
Hence, the ratio is 1.625%

Which equation below represents a line with a slope of - 2/3 that passes through the point (-4.5 , 10)?
A. y = - 2/3 x + 10
B. y = - 2/3 x +2.7
C. y = - 2/3 x + 7
D. y = - 2/3 x + 13
pls explain the answer if possible ^^
Answer:
Option C
Step-by-step explanation:
If a line passes through a point, then that point is called a solution to the line's equation. Substituting the x and y values of that solution into the equation will give a true statement. So, to find out which option is correct, we can substitute the x and y values of (-4.5, 10) into each equation and see if the result is a true statement.
Let's try this with option C. To make things easier, convert -4.5 into decimal form: [tex]-4\frac{1}{2}[/tex]. Substitute [tex]-4\frac{1}{2}[/tex] for x and 10 for y in the equation, then solve:
[tex]y = -\frac{2}{3} x+7\\\\10 = -\frac{2}{3} (-4\frac{1}{2} )+7\\10 = -\frac{2}{3} (-\frac{9}{2})+7\\10 = 3+7\\10 = 10[/tex]
10 does equal 10, so this is a true statement. Option C is the right answer.

Answer:
B. (2, 1)
Step-by-step explanation:
As a first guess you might say the right angle will be at the point that has the x-coordinate of A (2) and the y-coordinate of B (1).
You notice that the point (2, 1) is on the list of answer choices, so that is a good choice.
The coordinates of C could be (2, 1).

A factor of a number that, when multiplied by itself, gives the original number is called a square root.
The square root of 3 is 9.
The integer that has the nearest to the integer that has a square root of 3 is √10.
What is a square root?A factor of a number that, when multiplied by itself, gives the original number.
We have,
9 is a square root of 3.
The nearest square root of 3 can be 8 or 10.
The value of the square root of 8.
= √8
= 2.83
The value of the square root of 10:
= √10
= 3.16
The nearest can be determined by finding out the difference between each of its values with 3.
For √8,
= 3 - 2.83
= 0.17
For √10,
= 3.16 - 3
= 0.16
We see that √10 is nearest to the integer that has a square root of 3.
Thus the integer that has the nearest to the integer that has a square root of 3 is √10.

What is the graph of the function
f(x)=−⌊x⌋
Answer:
Step-by-step explanation:
The equation being shown in the question is the absolute value of x. Absolute values when graphed show up as a V-shaped graph pointing upwards. This is because whatever value is passed as an input will output a positive, regardless of whether the input is positive or negative. Meaning that both 4 and -4 will output 4. That is why the graph is a V-shaped because the outputs repeat for both positive and negative inputs. In this case since the negative is outside the absolute value brackets the positive value given from the absolute value of the input will be turned into a negative. So this will cause the V-shape graph to be reflected across the x-axis. As seen in the attached picture below.

A small airplane is approaching a stationary crowd at 100 meters per second. The engine of the plane is emitting a sound of 485 Hz. What is the apparent frequency as it approaches the crowd?
Answer:
695.87 Hz
Step-by-step explanation:
Using the equation for Doppler shift, the frequency of the apparent sound is f' = f(v ± v')/(v ± v") where f = frequency of sound emitted by the plane's engine = 485 Hz, v = speed of sound in air = 330 m/s, v' = speed of crowd(detector) = 0 m/s (since the crowd are stationary) and v" = speed of plane(source) = 100 m/s
So, f' = f(v ± v')/(v ± v")
f' = f(v ± 0)/(v ± v")
f' = fv/(v ± v")
Since the source moves towards the detector, we use a minus a minus sign in the denominator to get a shift upwards in frequency since a shift upwards means the objects are moving closer to each other.
So,
f' = fv/(v - v")
Substituting the values of the variables into the equation, we have
f' = 485 Hz × 330 m/s/(330 m/s - 100 m/s)
f' = 160050 Hzm/s ÷ 230 m/s
f' = 695.87 Hz

what is 10c + 20 = 40 C =
Answer: c = 2
Step-by-step explanation:
First you write out your equation: 10c + 20 = 40
Next, since the equation is adding, you can subtract 20 the constant on both sides of the equation:
10c + 20 = 40
- 20 - 20
The 20s cancel each other out and 40 - 20 is 20.
Our new equation looks like: 10c = 20
Now to find the value of C you are going to divide 10 on both sides because the equation is multiplying.
10c divided by 10 is just c and 20 divided by 10 is 2.
Therefore, you are left with c = 2

A boat covers 25 km upstream and 44 km downstream in t hours. Also, it covers 15 km upstream and 22 km downstream in 5 hours. Find the speed of the boat in still water and that of the stream.
9514 1404 393
Answer:
boat speed: (7t -95)/(6t² -110t +500)
stream speed: (37t -345)/(6t² -110t +500)
Step-by-step explanation:
The relation between time, speed, and distance is ...
time = distance/speed
The boat speed (b) is added to the stream speed (s) going downstream. The stream speed is subtracted going upstream. The given relations tell us ...
25/(b-s) +44/(b+s) = t
15/(b-s) +22/(b+s) = 5
This gives us 2 equations in 3 unknowns, so we can only provide a solution in terms of one of the unknowns. Since we are asked for the speeds, they will be provided in terms of t.
Subtracting the first equation from 2 times the second gives ...
2(15/(b-s) +22/(b+s)) -(25/(b-s) +44/(b+s)) = 2(5) -(t)
5/(b-s) = 10 -t
5/(10 -t) = b -s
Substituting for b-s in the second equation gives ...
15/(5/(10-t)) +22/(b+s) = 5
30 -3t +22/(b+s) = 5
22/(b+s) = 3t -25
22/(3t -25) = b+s
Adding the equations for the sum and difference of speeds, we get ...
(b-s) +(b+s) = 5/(10-t) +22/(3t -25)
2b = (5(3t -25) +22(10 -t))/((10-t)(3t-25)) = (95 -7t)/((10-t)(3t-25))
b = (7t -95)/(6t² -110t +500)
Subtracting the equations for sum and difference of speeds, we get ...
(b+s) -(b-s) = 22/(3t -25) -5/(10 -t)
2s = (22(10-t) -5(3t -25))/((10-t)(3t-25))
s = (37t -345)/(6t² -110t +500)
__
The speed of the boat in still water is (7t -95)/(6t² -110t +500) km/h.
The speed of the stream is (37t -345)/(6t² -110t +500) km/h.
__
Note that these solutions only make sense for values of t between 25/3 and 345/37, approximately 8.33 < t < 9.32. For t=9 hours, the boat speed is 8 km/h and the stream speed is 3 km/h.

The area of triangle QTU is 6 square units, and the area of triangle RSU is 6 square units. The dimensions in the figure below are labeled in units. What is the area of triangle STU in square units
Answer:
The area of a triangle is 1/2BH, or 1/2 times the base times the height.
If the area = 6, and B and H must both be whole numbers.
The area of the triangle ΔSTU is given by A = 12 units²
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the area of the triangle ΔSTU be represented as A
Now , the area of triangle ΔQTU is 6 square units, and the area of triangle ΔRSU is 6 square units
So , the base of the triangle ΔSTU = 6 units
The height of the triangle ΔSTU = 4 units
So , area of the triangle = ( 1/2 ) x Length x Base
On simplifying , we get
The area of triangle ΔSTU = ( 1/2 ) x 4 x 6
The area of triangle ΔSTU = 12 units²
Therefore , the value of A is 12 units²
Hence , the area of the triangle is 12 units²

Write the rational number as a decimal.
Answer: -2.2
Step-by-step explanation:
-10 is the most possible that can be divided by 5, resulting in -2.
The leftover 1 is divided by 5, resulting in .2.
The decimal ends up being -2.2.
Answer:
-2.2 or -1.2
Step-by-step explanation:
When you want to write a decimal as a fraction, you simply divide the numerator with the denominator. So when you divide -11 by five that would be a -2.2. Or if it is -1 1/5 the answer would be -1.2. I cant really tell what that number is.
